[1] Parents and educators battle over how much homework kids should have, and how often they should have it. This past school year, my eldest daughter's teacher did not assign too much homework, and often gave the kids extra time during class to get it done. Meanwhile, my daughter's dear friend — who attends the same school and is in the same grade — struggled nightly with her lengthy homework assignments. She had work to do every night, extra projects to complete, and assignments to complete over holiday break.
[2] So which was the lucky kid? Some might argue that my child was — she had more time to play, and spent less time stressing over assignments. Others might feel that my child was missing out on a key element of her education by not having what she was learning during the school day reinforced.
[3] To be honest, I'm not really sure which camp I'm in, but it's debates like this one that have sparked a homework revolution between parents and schools all over the country. A New York Times article reported that the school district in Galloway, N.J., is considering a proposal to limit weeknight homework to 10 minutes for each year of school — 20 minutes for second-graders, 30 minutes for third-graders, etc. — and ban assignments on weekends, holidays and school vacations. The school district in Pleasanton, Calif., is looking at a similar proposal. __________, other schools around the country are introducing homework-free holidays, no-homework nights, and goal-work — instead of homework — that can be completed throughout the school day.
[4] Most of these changes are in response to annoyed parents who see lengthy homework assignments competing with what little family time they have each day. The documentary "Race To Nowhere" spurred（激起）more debate by highlighting the unnecessary pressure on kids in today's educational system.
